Manipulating String while true PYTHON

I’m doing a student grade exercise, receiving a str with the student’s name, then int to know the grades(n1,N2,N3,N4). I made a while true, so it will always ask, until the user asks to quit, because the program drops asking if you want to continue with s/n.

while True:
aluno_nome = str(input("Digite o nome do aluno:"))
aluno = print("Digite notas aluno.")
n1=int(input("Nota 1:"))
n2=int(input("Nota 2:"))
n3=int(input("Nota 3:"))
n4=int(input("Nota 4:"))
final = (n1+n2+n3+n4)/4
#print("Aluno ",aluno_nome,"\nNota Final:",media)
sai = str(input('\nDeseja continuar[S/N]?').lower())
while sai != 's' and sai != 'n':
    sai = str(input('Deseja continuar[S/N]?').lower())
if sai in 'n':
    break
print("\nAluno ",aluno_nome,"\nNota Final:",final)

I want to know the easiest way, to print at the end the name of each student, and the grade of the same, such student in such, such student grade. I have to actually create a variable for each name and so save each of the 4 notes inside, but I can’t do it more "clean" with while true, and and do some counter to go creating and storing the name and final grade of the student.

    Do you want to show at the end of the loop a list of all input students and their final average? Would that be it?

You can use dictionary to save the data of each student, use a list to save them and when the user finishes typing, you make an iteration in the student list to display the final result, e.g.:

# cria um array de alunos
ar_alunos = []

while True:
  al = {} # cria dicionario aluno vazio

  # salva nome do aluno
  al['aluno_nome'] = str(input("Digite o nome do aluno:"))

  print("Digite notas aluno.")
  n1=int(input("Nota 1:"))
  n2=int(input("Nota 2:"))
  n3=int(input("Nota 3:"))
  n4=int(input("Nota 4:"))

  #calcula media das notas
  al['media'] = (n1+n2+n3+n4)/4

  #salva aluno no array de alunos
  ar_alunos.append(al)

  sai = str(input('\nDeseja continuar[S/N]?').lower())
  while sai != 's' and sai != 'n':
      sai = str(input('Deseja continuar[S/N]?').lower())
  if sai in 'n':
      break


# printa todas as medias  
print()
print("# Relatorio de medias #")
for aluno in ar_alunos:
  print()
  print("Aluno ",aluno['aluno_nome'],"\nNota Final:",aluno['media'])
